Potassium tetrapyrophosphate (Tetrasodium pyrophosphate ) is a whitish-colored powdered solid. It is toxic by ingestion, and/or inhalation. Contact with the substance should be avoided.
Tetrasodium pyrophosphate, also called sodium pyrophosphate, tetrasodium phosphate or TSPP, is a colorless transparent crystalline chemical compound with the formula Na4P2O7. It is a salt composed of pyrophosphate and sodium ions. Toxicity is approximately twice that of table salt when ingested orally. There is also a hydrated form, Na4P2O7 · 10(H2O).

【Production of Potassium Pyrophosphate】
1. Tetrasodium pyrophosphate is produced by the reaction of furnace-grade phosphoric acid with sodium carbonate to form disodium phosphate, which is then heated to 450 °C to form tetrasodium pyrophosphate.
2. Alternatively, it can be created by the molecular dehydration of dibasic sodium phosphate at 500 °C (932 °F).
